Diego Costa is one of the most efficient players Chelsea have managed to sign during the past few years. The Brazilian born Spanish international seems to be well worth the money considering he already has scored 8 goals since joining the Blues. According to Metro, the 25 year old is one of those investments who are worth their weight in gold, especially if the Chelsea hierarchy think back to the moment they decided to pay £50 million for Torres who in three seasons scored twice as much as Costa scored in his first couple of matches.

Even if Costa is not quite playing at full speed due to some hamstring problems, he is still making a serious impact as he showed last night against Sporting Lisbon in the Champions League. He will be even more effective in front of goal after he gets his health problems fully sorted out which is a scary thought for opposing teams. The striker not only helps the team’s stats but also influences the way some of his teammates perform. Players like Hazard can now focus entirely on making assists and creating goal scoring opportunities instead of worrying about scoring themselves.

With a shot accuracy of 85% Costa is currently the Premier League’s top scorer. He impressed the audience with an unexpected attitude especially if you consider his World Cup performance. It seems that he was in great pain while in Brazil and that is why he failed to show his true talents. Fortunately for Chelsea, Costa has recovered and is now capable of doing his job properly. The Blues seem to be set for the next couple of years as far as goal-scoring goes.
